Halloween // What's the "scariest/spookiest" footage you've viewed online?

Hey All, I'm trying to compile a list of the spookiest, scariest, or creepy ghost/cryptid videos (or similar) on YouTube. I know the jury is out as to whether ghosts are real or not but I'm looking for the most "realistic". My friends an I always compile a playlist on YouTube and have a watch party on Halloween. I'll post the playlist once we get a bunch of good videos added to it. Thanks for all your help and Happy Halloween!
